Choice to enable Master Valve per zone

    So doing a little homework - it looks like you can only GET certain zone information but not set (POST) settings. If so I could easily set Zone 1 to "Not master valve" do my fills, etc and then set Zone 1 to "Yes Master Valve".  Any thoughts there?

    I have the same request and concern. Most of my zones are well pumped water, but a few are city water (to eliminate brown bricks and rocks). Would love to see zones that specify that the pump is on or off.

    I would also welcome this functionality to click a checkbox for every channel. 

    All outputs of my HD16 lead to 24V relays. So one could switch a lighting or a fountain pump for the pond with not currently used channels of the RM. This could make additional remote controls or timers unnecessary. Thank you!

    Yes this feature would be great

    This feature would be great, but I think the more general solution includes:

    1) allow more that 1 circuit to run at a time (as implied by the ability to have a master and a separate zone, but make it arbitrary).  This may have special constraints multiple valves draw too much water (constrained by sum of zone flows).

    2) allow any zone to trigger a second zone (to run a pump, master, valve, drain, etc).  This may be constrained to never allow 3 zones if power is limited (if zones cascade to 3 valves, etc).  This may also fall under the constraint of multiple circuit flow limit as noted in 1) above.  This may imply a "master" flow rate is counted in a special way sinces it doesn't add to the flow through sub zones.

        This could be setup as allowing 0 to 3 zones on a controller to be "master" for different purposes.  That would reduce the bit-depth for each zone to associate with another simultaneous zone.  I don't think the bit savings help, so the 2 points above seem the most general.

    An alternative would be selling accessories or sharing information to provide this capability external to the controller.  A simple ebay 24vac dpdt (double pull double throw) relay for $3 from ebay can allow 1 output to connect a signal and  24vac power supply to 2 devices without any interference with the rain machine or enabling power to a master valve.  There may be better variations/ideas for features or external accessories, so followups may help many with similar needs.

    Yep, I love the idea of adding this flexibility... 

     

    as an example I'm testing my system for leaks, I want to test the pipe between the master and the valves without turning the other valves on

    I would like to have this implemented. It will solve a lot of workarounds.

    This is one of the first things I asked for when I purchased the HD-16 back in 2015. I only use a master valve for the zones in my garden because those valve boxes are in back, connected by a poly pipe from the main valve banks in front of the house. I did not want that poly pipe under constant full pressure the entire watering season. However, not being able to assign which zones need the master valve opened means the master valve sits on for no reason for all of the hours that my 6 lawn zones and other drip zones connected upstream from the master are watering (which is unnecessary wear on the master's solenoid, pressure on the pipe).
